介绍无线传感器网络中常用的质心定位算法和APIT定位算法;在Matlab2010仿真环境下,对质心和AIPT定位算法进行仿真;主要通过调整未知节点通信半径、信标节点比例和网格边长等参数进行仿真;并通过定位误差图形式比较两种算法的性能。仿真实验结果表明APIT定位算法优于质心定位算法。

This paper introduces the centroid localization algorithm and APIT localization algorithm in Wireless Sensor Network. The centroid and AIPT localization algorithm are simulated in the Matlab2010 simulation environment. The simulation is carded out mainly by adjusting the unknown node communication radius, the ratio of beacon nodes and grid side length. The performance of the two algorithms is compared with the localization error chart. The simulation results show that the APIT localization algorithm is better than the centroid localization algorithm.
